Why is it needed? To ensure continuity of the electricity service in Lombardy, Terna will create a new 380 kV section at the existing 220 kV Magenta substation with very short connections to the 380 kV “Turbigo-Baggio” power line. The new section and relative connections will allow a direct link to the 132 kV extra-high-voltage grid, guaranteeing reliability, security and operating flexibility for the grid in the area between the 380 kV substations of Turbigo and Baggio.
The project. The project will see sections of the four 132 kV lines buried underground. This work to bury sections of the lines represents application of the “Memorandum of Understanding on the Strategic Objectives of Strengthening and Rationalisation of the NTG in Lombardy”, between the Lombardy Regional Authority, Parco Lombardo della Valle del Ticino and Terna, signed on 5 January 2010. Around 325 metres of 380 kV lines will be demolished, and the burying of sections of the 132 kV line managed by the Magenta substation will begin. All demolition work will occur within the Parco Lombardo della Valle del Ticino area. Planning of the work has been carried out in full respect of the goals of environmental safeguarding, protection and improvement. There is no direct interference with Natura 2000 sites, which are far enough away not to warrant a concern for the landscape. The substation area occupies agricultural land and therefore has no impact on forests or special habitats. Because of the significant length of overhead lines due to be dismantled, this work will have an important positive impact on the landscape.
The stages. Following the MoU signed on 5 January 2010 with the Lombardy Regional Authority and Parco Lombardo della Valle del Ticino, Terna has begun consultation with the Municipality of Magenta in order to share its proposals. The Municipality of Magenta has developed the plan for grid development works proposed by Terna in the municipal territory and its content was unanimously approved on 9 July 2014. After the usual, in-depth discussion with citizens and local authorities, along with a “Terna Meets” event held on 14 October 2015, the project received authorisation on 7 March 2018.
